My friend and I were in the back yard sitting by the pool when I looked up into the bright clear blue sky and noticed what looked like a star. I kept watching it and it just hovered there for a long time, kind of changing shapes although it was so high it was really hard to tell. It looked like it split into two and one moved over to the right of it and then went back and rejoined the first. I got my camera and took photos, which I will email to you. Please look at them and tell me what you think. If you zoom in on the object you can tell it is clearly not a star, and it wasn't moving so it wasn't a plane or helicopter or balloon. On the fourth picture I took you can see the object separating on the bottom. After 15 minutes or so, hard to tell, I was so entranced, it just faded away and I could no longer see anything in the sky.
